the fact that the fsu immigrants earn more than the native-born israelis already suggests that the salary is mainly merit-based. despite the language barrier, they succeed much better than the rest of the population. these researchers, as well as other statistitians, should look beyond the 'same' profession/job description criteria. for example, how many arabs or 'ethiopians' graduate at the top of the class compared with the 'russians' or sabras. the top picks always have better salaries. not everyone who graduates actually knows much, too many people have worthless degrees. the statistics must look at this as well.
